state-machine obj in store cause infinite loop

[xlinx]

state-machine for object CMD_Mode_All is objs pool which little like an ENUM in js.
The function nextModeX is a next/prev choicer function which I use for quick next objs from the obj-pool. When I use it in Sore, it causes an infinite loop, even use shallow. Is there any way I can use that in-store?
in my view the value in store same as other obj, like JSON obj. but here cause infinite loop...

Thanks, guys.

btw, why the code area below doesn't change the color; I have been use ` ` ` code```

const CMD_Mode_All = {
    M1: {name: "m1", info: "info1", STYLE1: "1"},
    M2: {name: "m2", info: "info2", STYLE2: "2"},
    M3: {name: "m3", info: "info3", STYLE2: "3"}

};
export const useStoreX = create((set, get) => ({
   CMD_Mode_NOW:CMD_Mode_All.M1,
    setCMD_Mode:(by) => set(() => ({CMD_Mode_NOW:nextModeX(by, CMD_Mode_All)})), // <== infinite loop render
    setCMD_Mode:(by) => set(() => ({CMD_Mode_NOW:by})), // <== infinite loop render also
}));

    setCMD_Mode(nextModeX(CMD_Mode_NOW, CMD_Mode_All)); // <== call it outside, infinite loop render also

export function nextModeX(m_now, all_models, next_prev=true) {
  let r={};
  if(!Array.isArray(all_models)){
    let keys=Object.keys(all_models);
    let nowIndex=keys.findIndex((e) => {return all_models[e].name===m_now.name});
    let nextIndex=0;
    if(nxt_pre)
      nextIndex=(nowIndex+1)%keys.length;
    else
      nextIndex=(nowIndex-1)<0?keys.length-1:(nowIndex-1);

    console.log("[switchANYMode][nowIndex=]",nowIndex,nextIndex);
    r=Reflect.get(all_models, keys[nextIndex]);

  }else{
    let length=all_models.length;
    r=all_models[0];
    for (let i=0;i<length;i++){
      if(JSON.stringify(all_models[i]) === JSON.stringify(m_now)){
        let nextIndex;
        if(nxt_pre)
          nextIndex=(i+1)%length;
        else{
          nextIndex=(i-1)<0?length-1:(i-1);
        }
        console.log("obj nextIndex",nextIndex,all_models[nextIndex]);
        r=all_models[nextIndex];
        break;
      }
    }
  }
  return r;
}
